IMPROVEMENT IN; STEAM-DEVICES FOR WARMING RAILROAD-CARS, AND OTHER PUR- POSES.

The Schedule referred to in these Letters Patent and making part of the same.

' Be it known that I, ARGHIBALD 0. CRAB-Y, a resident of the city of Utica, in the State of New York, have invented a new and useful Improvement in the Mode or Process of Heating Railway-Cars by Steam.

The nature of my invention consists in the peculiar construction of the steam-car, the arrangement of the steam-generator, disconnected from the steam-engine, as a device in the use of steam as a heating-agent; and I hereby declare that the followingis a'fnll and accurate description of the construction and operation thereof, reference being had to the accompanying drawings, and to the letters of referencemarked thereon, making part of this specification, in which- Figure 1 is a perspective view of. the steam and baggage-car, the partition between theapartment containing the steam-generator and that designed for the conveyance of baggage, the ecceutiic attached to one of the axles of the truck, and the smoke-pipe of the steam-generator.

Figure 2 is a rectangle view of the steam-car, showing the positions of the steam-generator, the tank, the

. apartments of the steam and baggage-car, and the po sitions of the tank, the fire-box, and ash-basin chamber.

Figure 3 is a vertical view of the tank, and of the fire-box, enclosed, on three of its sides, by the tank.

Figure 4 is the eccentric, attached to'an axle-of a truck, the collar, and the vertical rod which operates the pump of the steam-generator.

A, fig. 1, is the steam-car.

B is the section of the car which contains the steamgenerator.

G is the baggage-room.

D D are the passages into the car.

E, fig.,2, is the steam-generator.

I is the air-tight fire-box.

G G is the air-tight tank.

H is the eccentric, on, and firmly attached to one of the axles of the truck.

I is the truck.

K is the collar.

L is the vertical rod connected with the collar, and which operates the pump of the steam-generator.

M, fig. 3, is the tank.

N is the steam-generator.

0 is the fire-box.

P is the baggage-masters' room.

The steam-generator in the steam-car is designed as a substitute for the steam-generator which is connected with the boiler of the locomotive, when accident or circumstances prevent the transmission of steam from the locomotive to the passenger-cars.

The tank, when it encloses the fire-box, will prevent the escape of heat, and, by heating the water in the tank, may furnish hot water to the boiler of the steam generator.

The steam-generator, with its tank and fire-box, may be applied to heating dwelling-houses and other buildings. It may be connected with a range, grate, stove, or. other appm-tenances for warming buildings, or for cooking, in a similar manner to the connection between thesteam-generator and boiler of the steamen me.

The tank, which encloses the fire-box and ash-basin chamber of a steam-engine or steam-generator, may be used as an appliance to prevent the overheating the room occupied by the steam-generator or steam-eugine; and the water from the tank may be used for household-purposes, when the drip, or water condensed from the steam, is returned to the boiler of the steam engine, or of the steam-generator.

In fig. 1, Q represents a steam-pipe, extending over the cars, and 4 R. represents the exhaust-steam pipe, connected to the steam-generator, and entering into pipe Q.

Having thus described my invention,

What I claim therein as new and useful, and desire to secure by Letters Patent of the United States, is-

1. The combination and arrangement of the steamcar, and the enginery pertaining thereto, when constructed substantially as herein set forth.

2. The steam-generator and its mechanical devices, when disconnected from the locomotive, and constructed substantially as herein set forth.

3. The arrangement of the eccentric and its immediate devices, whereby to operate the pump of the steam-generator, substantially as herein described.
